Nervous System Final

Central nervous system

Structural nervous system subdivision that consists of the brain and spinal cord

receptor, sensory neuron, integration center, motor neuron, effector

Which of the following is the correct sequence in a typical reflex arc?

oligodendrocytes

Which of these neuroglial cells forms the myelin sheath in the central nervous system?

dura mater, arachnoid mater, pia mater

Which one of the following represents the correct sequence from outermost to innermost layers of the meninges?

Schwann

________ cells form the myelin sheaths around nerve fibers in the PNS.

Interneurons (association neurons)

________ connect sensory and motor neurons in neural pathways and their cell bodies are typically located in the central nervous system.

Autonomic

________ reflexes include the secretion of saliva, changes in the size of our pupils, and digestion involve the activities of smooth muscles.

hypothalamus

coordinates both the autonomic nervous system and the activity of the pituitary, controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity

false

A sensory neuron carries stimuli from the central nervous system to the effector. true or false

frontal lobe

A stroke in the primary motor area has caused Don to lose control over his skeletal muscles on the right side of his body. What lobe of his brain was damaged?

hypothalamus

Control of temperature, endocrine activity, metabolism, and thirst are functions associated with the ________.

false

Difficulty in breathing may reflect damage to respiratory centers located in the cerebellum. true or false

Autonomic nervous system

Structural nervous system subdivision that consists of spinal nerves and cranial nerves

somatic sensory

Fibers that carry information from the skin, joints, and skeletal muscles to the central nervous system are ________.

Sensory (afferent) division

Functional nervous system division that carries information from the central nervous system toward effectors

Peripheral nervous system

Functional nervous system subdivision that carries information toward the central nervous system from receptors

myelinated

Impulse conduction is fastest in neurons that are ________.

white; gray

Myelinated fibers (tracts) form ________ matter while unmyelinated fibers form ________ matter.

breathing

One of the major functions of the pons is to control ________.

false

One of the major functions of the pons is to produce releasing factors that control the function of the anterior pituitary. true or false

sympathetic nervous system

Preparing the body for the "fight-or-flight" response during threatening situations is the role of the ________.

Motor (efferent) division

Subdivision of the motor division responsible for controlling involuntary events

The brain and spinal cord are protected and cushioned by three connective tissue membranes that are collectively called ________.

false

The central nervous system includes the spinal nerves and cranial nerves. True or false

true

The collection of spinal nerves at the inferior end of the spinal cord is called the cauda equina.

The delicate innermost membrane, or meningeal layer, that clings to the surface of the brain and spinal cord is known as the ________ mater.

longitudinal fissure

The fissure in the brain that separates the two cerebral hemispheres is called the ________.

synaptic cleft

The gap between two communicating neurons is termed ________.

corpus callosum

The large fiber tract that allows communication between the two cerebral hemispheres is called the ________.

brain stem
